| Description: UTEC5040 is an Ultra High Molecular Weight Polyethylene with a molecular weight about 10 times higher than High Density Polyethylene (HDPE) resins. This extremely high molecular weight yields several unique properties to this polymer such as high abrasion resistance and impact strength and low coefficient of friction, what makes it a self-lubricating material. Applications: Applications which require high wear resistance – technical parts RAM extruded and compression molded sheets, rods and profiles.&& |
